Justification:
This species is only known from the holotype and paratype collected in the Straits of Magellan, and has not been recorded since 1970. Although this is not a heavily surveyed area, localized threats such as shipping, dredging, and fishing activities may pose a threat to this species. It is listed as Data Deficient. More information is needed on this species distribution, population, biology, life history and impact of potential threats.

The only two specimens known were taken at mid-channel waters, from 300-302 m depth (Wisner and McMillan 1995).

The copulatory organ is absent for this species. The gonads of hagfishes are situated in the peritoneal cavity. The ovary is found in the anterior portion of the gonad, and the testis is found in the posterior part. The animal becomes female if the cranial part of the gonad develops or male if the caudal part undergoes differentiation. If none develops, then the animal becomes sterile. If both anterior and posterior parts develop, then the animal becomes a functional hermaphrodite. However, hermaphroditism being characterised as functional needs to be validated by more reproduction studies (Patzner 1998).
